Two Solana supply reform proposals, SGP-0002 and SGP-0003, are in the final week of their governance discussion period, which ends Aug. 22 at 15:13 UTC. Both cleared the 15% stake-support threshold to move into discussion, with Helius and Jupiter the largest named backers, pledging 16 million and 12.47 million SOL respectively.
Disinflation and validator economics
SGP-0002 would double the annual disinflation rate from 15% to 30%, cutting the time to reach 1.5% terminal inflation from about 5.7 years down to roughly 2.8. Over six years, SOL issuance would drop by about 18.9 million tokens, a 2.6% reduction.
That faster path comes with a cost for stakers. Under the proposal, staking yield would fall from 5.84% to 4.34% after one year, then to 3% after two, and 2.25% after three. The math also gets tighter for validators. At baseline, 290 validators would become unprofitable under the new schedule, and that number rises to 320 after three years.
Fee burn mechanics
SGP-0003 takes a different angle, reworking transaction fees. It would introduce a 2,500-lamport inclusion fee paid to the block leader, while a separate usage-based resource fee gets burned in full. The resource fee steps through 0.1, 0.25, and 0.5 lamport per cost unit.
If adopted, daily burns could jump from roughly 648 SOL to between 1,500 and 1,800 SOL at the first rate, and between 7,500 and 9,000 SOL at the terminal rate. That would shift how much users pay based on how resource-heavy their transactions are. Efficient transactions might cost less at the terminal rate, while bulkier ones would carry a bigger price tag.
The trade-off for stakers and validators
Together, the two proposals aim to slow SOL's supply growth and make the network's fee market more dynamic. But they don't come without friction. The validator profitability numbers in SGP-0002 have already raised questions about whether smaller operators can survive the yield squeeze.
Supporters like Helius and Jupiter have put real stake behind both ideas, but the governance process is still open. The discussion period ends Aug. 22 at 15:13 UTC, after which the proposals move to a formal vote. Until then, the numbers are on the table for anyone with stake to weigh in.
